Retail sales fell flat in July, according to data released Wednesday by the US Commerce Department. If the retail sales trend continues, some experts say, we may have to lower our expectations for economic growth in 2014.

US consumers didn’t boost their shopping in July. If that’s a one-month blip, experts say, the economy’s growth should remain on track. If it’s not, it could be bad sign for the whole year.

Retail sales posted no growth in July – 0.0 percent over June, according to a report released Wednesday by the US Commerce Department. Analysts had expected slight growth, to the tune of about 0.2 percent. It was the measure’s worst performance in six months, since lousy winter weather hampered spending at the beginning of the year.

Consumer spending in general makes up about two-thirds of overall gross domestic product, and concerns over soft retail sales come off the heels of slow consumer spending figures in recent months. Those figures, however, slowed in part due to falling health-care costs. “The data in the retail sales report encompass spending on goods only, and hence do not encompass changes in healthcare spending," Joshua Shapiro, chief US economist with the research firm MFR Inc., writes vie e-mailed analysis.

But Mr. Shapiro argues that other indicators, including labor market conditions, will weigh more heavily on overall economic growth.

“Today’s data for July were clearly disappointing,” he writes. “Still, with a wide array of labor market indicators flashing increasingly optimistic signals, and the data reported today subject to revision (sometimes considerable with this release), we are not panicking based on a single month’s result. However, if next month’s report does not show considerably better outcomes, we (and most other analysts) will need to reassess our Q3 forecasts for consumer spending in particular and overall GDP in general.”
